Cf. Shu et al., A NEW SYNTHETIC APPROACH FOR NONLINEAR-OPTICAL CHROMOPHORES POSSESSING ENHANCED THERMAL-STABILITY, Tetrahedron letters, 37(39), 1996, pp. 7055-7058
A synthetic strategy for NLO chromophores containing cyclic-locked, co
njugated triene segment has been developed. The incorporation of the e
thylenic bonds into a 6-membered ring resulted in enhanced thermal sta
bilities of chromophores. Copyright (C) 1996 Elsevier Science Ltd
