- 中文摘要: Hula-twist is a rapid diabatic process of photoisomerization. It is not volume-demanding and its stereochemical consequence is simultaneous isomerization of a double and a single bond. Recent new examples include diene, styrene, stilbene, diphenylbutadiene and other derivatives in organic glasses at liquid nitrogen temperature. In systems where two different modes of HT are possible, a high regioselectivity was observed. Possible involvement of the volume-conserving mechanism of isomerization in primary processes of photosensitive biopigments is discussed.
