Quinone dimers connected with acetylene (QAQ) and diacetylene linkages (QAAQ) have been synthesized and their structure and electronic properties studied. X-ray analysis, DFT calculations, and UV–vis measurements showed that, unlike directly connected quinone dimers ( QQ ), they had planar and thus efficiently extended π conjugation systems. keluaran nevada togel
