Se and Te atoms do not conjugate their lone electron pairs with the -conjugated system and therefore only increase the contribution of the quinoid form of chalcogenophene unit. 2,7-substituted carbazole derivatives present stronger carbazole-chalcogenophene conjugation than 3,6-substituted derivatives. One 3,6-substituted carbazole derivative and triphenylamine derived polymers were found to have promising electrochromic properties with black electrochromism.

Observation of Dual Room Temperature Fluorescence–Phosphorescence in Air, in the Crystal Form of a Thianthrene Derivative

“…1,2 Spin-orbit coupling interactions induced by the nπ* transitions and the heavy-atom effect caused by the presence of sulfur, lead to its remarkable phosphorescent properties. [3][4][5][6][7] As a result, thianthrene and its analogs are mediocre photoluminescence emitters in conditions where the triplet state is effectively quenched by the surrounding environment, i.e. in solution or in the presence of oxygen.…”

Recent Advances in the Oxone-Mediated Synthesis of Heterocyclic Compounds

“…Chalcogenophenes are a valuable class of heterocyclic compounds, which play an important role as building blocks in organic synthesis [42], in the development of new materials [43,44], and in the prospection of new drugs in the pharmaceutical industry [45,46]. Due to these important features, the search for the development of simple and efficient methods to access chalcogenophenes has attracted interest during the last decades.…”

Synthesis and characterization of a new benzobisoxazole/thiophene derivative polymer and the effect of the substituent on the push/pull properties

“…Interestingly, either the low bandgap levels or optical properties are fundamental characteristics of these materials. Based on the existing literature on polymeric systems with good optical properties, the most studied compounds are homopolymers of pyrrole, carbazole, fluorene, and benzothiadiazole 17–21 . It is worth to note that benzobisoxazole compounds (as an acceptor polymer) is a polymer family that has scarcely been explored to obtain CPs with these qualities 22 .…”
