A new building block, bis(thiophene vinyl)-pyrimidine, for constructing excellent two-photon absorption materials: synthesis, crystal structure and properties†
Abstract
Two new molecules (Py1 and Py2) of D–π–A–π–D motif, where the –π–A–π– moiety is bis(thiophene vinyl)-pyrimidine as a building block, have been designed and synthesized via the Knoevenagel and Suzuki coupling reactions. The X-ray single crystal structure analysis of Py1 showed good coplanarity in the whole building block. Their two-
