A photochemical active triangle terarylene was synthesized and the photochromic behavior was investigated. Its photochromic reactivity can be strongly suppressed by selected oxidization of the sulfur atoms in the molecules. Reactivated photochromic reactivity was obtained by deoxidization of the S, S-dioxide moieties. The suppressed photoactivity of the oxidation state was attributed to the stronger intramolecular hydrogen bonding interactions.
合成了一种具有光化学活性的三角形并三苯，并对其光致变色行为进行了研究。通过对分子中硫原子进行特定氧化，其光致变色反应活性可被强烈抑制。通过对二氧化硫部分进行脱氧，可重新获得光致变色反应活性。氧化态下光活性的抑制归因于更强的分子内氢键相互作用。
