Abstract:
Methods for the synthesis of keto derivatives of the little studied naphtho[1,8-bc]thiophene system have been developed. Using the readily available benzothiophene derivative 6,7-dihydrobenzo[b]thiophen-4(5H)-one 4, a 3-keto-naphtho[1,8-bc]thiophene 14 was synthesized by a tin(IV) chloride catalyzed cyclization of the acid chloride derivative of the saturated acid 13b. The bicyclic ketone 4 was also used to prepare the keto-sulfoxide 7, which was cyclized to the 4-keto-naphtho[1,8-bc]thiophene system 9 in a Pummerer-type rearrangement.

Derivatives of $\alpha$-terthienyl bearing polar functional groups were synthesized either by: (1) introduction of electron-withdrawing and electron-donating at C-5 and C-5$\sp{\prime\prime}$; or (2) c

Abstract:
Although tricyanovinylated thiophene derivatives have been demonstrated to possess large molecular nonlinearities, their use in practical electro-optic devices utilizing high temperature processing conditions is somewhat limited by the low thermal stability (Td ≈ 250 °C) of the tricyanovinyl group. Furthermore, the tricyanovinyl group is very sensitive to many polar solvents which are commonly employed in the curing and processing of polyimide based electro-optic materials. For this reason, we modified some of the highly active tricyanovinyl derivatives with the objective of achieving tradeoff
