The article conveys some information:
Herein, a series of hetero polycycles which show optical response toward chem. stimuli were synthesized from trithiasumanene (I, TTS). TTS is transformed into the ortho-quinone form II, which then undergoes three-component Debus-Radziszewski reaction with aldehydes RCHO (R = H, C6H5, 4-CH3C6H4, 4-IC6H4, Q) and ammonia to give oxazole-fused TTS III. The thiophene rings on III (R = C6H5, 4-CH3C6H4, 4-IC6H4) are selectively oxidized to thiophene-S,S-dioxides, affording IV. It was found that the electronic structures of these compounds III and IV are governed by the substituents on the oxazole moiety and oxidation state of the thiophene ring. Moreover, these hetero-polycycles exhibit optical responses toward different chem. stimuli. Particularly, compounds III (R = Q) and IV (R = C6H5) can serve as fluorescence detectors for harmful chem. sulfide ions (S2-/HS-) and aniline, resp. This work indicates that TTS is a promising precursor for the creation of responsive materials. In the part of experimental materials, we found many familiar compounds, such as 4-Iodobenzaldehyde(cas: 15164-44-0Recommanded Product: 15164-44-0)
4-Iodobenzaldehyde(cas: 15164-44-0) is used in synthesis of 4-[2-(trimethylsilyl)ethynyl]benzaldehyde, 5,15-dimesityl-10-(3-[2-(trimethylsilyl)ethynyi]phenyl}-20-(4-iodophenyl)porphyrin, and 5,15-dimesityl-10-[3,5-bis{2-[4-(N,N’-difluoroboryl-1,9-dimethyidipyrrin-5-yl)-phenyl]ethynyl}phenyl]-20-(4-iodophenyl)porphyrin.Recommanded Product: 15164-44-0
