Abstract: New thiophene cpds. are 5-alkylthiothien-2-yl-Hg acetates and 5-alkylthio-thiophene-2-aldehyde derivs. of formula (I), where R=1-22C alkyl; X=-Hg-OCOCH3 or -CH=B; and B=a substd. C or N atom. More specifically X=-CH=C(CN)2, -CH=CH-Pyr+A-, -CH=CH-Phe-R2, -CHC=NOH or -CH=N-NH-Phe-R2; Pyr+=N-R1-substd. pyridinium-4-yl; R1=1-22, esp. 12-22C alkyl; Phe=p-phenylene; R2=a substit. more negative than H; A-=an anion; R=12-22C alkyl, esp. Me. USE/ADVANTAGE - (I) and 2-(1-22C)-alkyl-thiophene-5-aldehyde (II) are used for nonlinear optical (NLO) purposes; and some (I) are used in laminates with at least a mono-mol. layer of (I) on a substrate (claimed). These laminates can be structurised to 2D waveguides. (I), which have donor and acceptor substits., have absorption max. below 500, pref. below 450, esp. below 400 nm, high stability towards the atmos., elevated temps. and light and high NLO activity.
