A new derivate of tetracene (DTTA) was synthesized and characterized. From the UV spectrum, compound DTTA showed more stability than rubrene towards photo–oxidization in solid state. The increased stability of DTTA could be explained by the lower energy level of HOMO. Crystal structure is similar to that of rubrene, and based on the calculated results from the Pw91pw91/6-31 g software, good performance of DTTA is expected. [ABSTRACT FROM AUTHOR]

A new thiophene/anthracene derivative, 2,5-di (anthracen-2-yl)thieno [3,2-b]thiophene (2,5-DATT) which integrates excellent charge carrier transport property with the highest mobility of 0.92 cm2 V−1 s−1, high fluorescence quantum yield of 46.08% and high photoresponsivity is developed. Ultrasensitive UV phototransistor with responsivity up to 1.5 × 104 AW−1 and detectivity exceeding 3 × 1015 Jones is also demonstrated. These results show a feasible method for designing and synthesizing multifunctional materials. A new organic semiconductor 2,5-di (anthracen-2-yl)thieno [3,2-b]thiophene (2,5-DATT) is designed and synthesized. The excellent optoelectronic properties make 2,5-DATT a good candidate applied to multifunctional optoelectronic devices and show a feasible method for designing and synthesizing multifunctional materials.
