Several new rigidified heptamethine cyanine dyes bearing different N-alkyl chains were readily prepared by a novel semi-catalyzed method. All dyes displayed absorption within the so-called “phototherapeutic window”. In order to improve the structural versatility of the dyes, a Cl atom was incorporated in the exocyclic conjugated bridge present in the polymethine chain. In some cases the Cl underwent an unexpected in-situ substitution by a third oxygenated heterocyclic group, depending on the solubility of the chloro dye in the reaction solvent. Two possible mechanisms for the formation of these triheterocyclic dyes are proposed. The full spectroscopic characterization of all the cyanines synthesized is described.

3-Aminothiazolo[3,2-a] pyrimidinium salts (I; R = H, OMe) were prepared in 47-71% yield by treating 6-substituted 2-mercaptopyrimidines with Ph α-cyanobenzylbenzosulfonate, α-bromopropionitrile, or Et bromocyanoacetate and heating. Vilsmeier reaction (DMF, POCl₃) of the pyrimidinium salts led to Me formylation in the 5 position and to formation of a new heterocyclic system (thiazolopyrimidopyrimidine). The formyl-substituted thiazolopyrimidopyrimidines were separated as crystalline dark-blue substances having in addition to intense UV absorption bands a less intense, broad absorption band at ∼600 nm with well expressed vibrational structure. The thiazolopyrimidopyrimidines were treated with N-containing heterocyclic quaternary salts or nucleophilic agents (malonodinitrile) to give polymethine dyes.

Abd El-Aal, R. M. published the artcileSynthesis and physicochemical studies of some new quinolinoxazine pentamethine cyanine dyes, Quality Control of 606-55-3, the publication is Arabian Journal of Chemistry (2017), 10(1), 82-90, database is CAplus.

Polymethine cyanine dyes belong to a well-known class of organic compounds, which have been used in photog. and as information storage in laser technol. A series of novel cyanine dyes were synthesized through the formylation of quinolinium[b,c]1,4-oxazine-chloride salt 1. Reaction of compound 2-chloro-3-formyl-quinolinium[b,c]1,4-oxazine-chloride salt 2 with different molar ratios of 2(4)-Me substituted heterocyclic in basic catalysis afforded the corresponding 2-chloroquinolinium[b,c]1,4-oxazine-chloride salt-3[2(4)]-dimethine (3a-c), quinolinium[b,c]-1,4-oxazinechloride salt-2,3[2(4)]-pentamethine (4a-c) and quinolino[b,c]1,4-oxazine-6yl[2(4)]-monomethine-/2,3[2(4)]-pentamethine cyanine dyes (5a-c) resp. The structure of the dyes was characterized by elemental anal., visible absorption, fluorescence emission, IR, ¹H-NMR and mass spectroscopy. A comparison of the visible absorption maxima between compounds 3b, 4b and 5b showed that asym. mono-pentamethine cyanine dye 5b reveals a bathochromic shift than both dimethine 3b and pentamethine cyanine dyes 4b. The absorption spectra of dyes were investigated in organic solvents. The results indicated that the excitation for their color is a simple charge-transfer from oxygen atom of oxazine nucleus and/or nitrogen atom of pyridine (quinoline) nucleus to N-quaternary salts in di-, penta- and mono-/pentamethine cyanine dyes resp. These dyes showed pos. solvatochromism with increased solvent polarity.

Solvent effects on the lowest-energy electronic transitions of 2 merocyanines derived from quinoline were studied using 9 different solvent parameters reported in the literature. Relative merits and deficiencies of different parameters were assessed. From the correlation results, attempts were made to propose a solute-solvent interaction mechanism. For an assorted set of 19 solvents, as well as for a set of 9 hydroxylic solvents, excellent results are obtained with correlation equation involving E_T(30) and Hilderbrand’s solubility parameter δ_H.

The fluorescence of novel crown ether styryl dyes and their complexes with sodium cation was studied. The fluorescence quantum yield of crown ether styryl dyes is higher than that of dyes not containing crown ethers. While absorption and fluorescence spectra of a styryl dye are shifted to high frequency regions, its fluorescence quantum yield in the absence of photoisomerization is practically unchanged, and the rate constant of its fluorescence quenching rises as it forms a complex with the metal ion. The relaxation processes of photoisomerization and recoordination are considered. The adiabatic change of metal ion coordination in the crown ether may proceed in the excited state. The trans-cis photoisomerization of styryl dyes and their metal complexes is a barrierless reaction.

Thin films of mol. aggregates of pseudoisocyanine were obtained. Delocalization length of exciton wave function was measured with an assumption that an absorption line width is defined by disorder induced mixing of the lowest states of the 1-exciton band. Predicted effect of size enhancement of the nonlinear optical properties for mol. aggregates was observed The assumption used to determine the delocalization length coincides with the observed optical nonlinearity size enhancement.
