摘要：
Verdazyl radicals have been obtained from non-symmetric alkadiynyl ethers ofp-hydroxybenzaldehyde. Using these radicals, the effect of the distance between the conjugated diyne fragment and the bulky tetrazinyl substituent on the ability to solid-state polymerization under UV irradiation has been studied. It has been shown that the rate of solid-state polymerization (accompanied by the preservation of the radical site) is increased with an increase in the number of methylene groups in the alkadiyne fragment.
