7-R-anthra[2,3-b]thiophene derivatives (1, R = H, Me, i-Pr, MeO) are prepared in three steps (in average overall yield >50%) starting from (E)-4-RC6H4CH2(HOCH2)C=CI(CH2OH). The latter are commercial or readily prepared from 2-butyne-1,4-diol and ArC... Read More about Syntheses of 7-substituted anthra[2,3-b]thiophene derivatives and naphtho[2,3-b:6,7-b’]dithiophene.

Capturing waste heat energy with charge-transfer organic thermoelectrics (2018)
Journal Article

Electrically conducting organic salts, known for over 60 years, have recently demonstrated new abilities to convert waste heat directly into electrical power via the thermoelectric effect. Multiple opportunities are emerging for new structure-propert... Read More about Capturing waste heat energy with charge-transfer organic thermoelectrics.

Synthesis and thermoelectric properties of 2- and 2,8-substituted tetrathiotetracenes (2018)
Journal Article
