A radical solution: The photochemical instability and insolubility in organic solvents of pentacene derivatives prevent their use in molecular electronics. These issues were solved by using pentacene derivatives with stable radicals (Y=radical moiety, 1 a and 2 a) that have a lifetime of 2077 min in organic solvents under ambient light. The corresponding nonradical pentacene derivatives (Y=radical precursor
自由基溶液:并五苯衍生物的光化学不稳定性和在有机溶剂中的不溶性阻止了它们在分子电子学中的使用。这些问题通过使用并五苯衍生物与稳定的自由基(Y =自由基部分,解决了1和2)具有的2077分钟在有机溶剂中在环境光下一生。相应的非自由基并五苯衍生物(Y =自由基前体,1b和2b)在曝光时会衰减。
