ABSTRACT:
The present invention provides a thiophene derivative and the polymer thereof as expressed in the following formulas, which will respond to light and electricity and which are best suited for use as photorecording materials and light-electricity conversion elements. ##STR1## where n and m are independent integral numbers greater than 0; R.sub.1 is a hydrogen atom, a halogen atom or a trialkylsilyl group; the R.sub.2 s together with the ethylenic linkage form a ring and said R.sub.2 s taken together are an optionally substituted alkylene group or --COOCO-- or the R.sub.2 s independently represent cyano; and R.sub.3, R.sub.4 and R.sub.5 are hydrogen or alkyl.
