摘      要：Challenges of achieving efficient photodimerization of azaanthracene derivatives remain due to the low selectivity and slow reaction *** this paper,cucurbit[10]uril(CB[10]),with the largest rigid and hydrophobic cavity among CB[n]s,was used to affect the photodimerization reaction of four water-soluble 1-(2-)substituted azaanthracene derivatives(1-4).It revealed that 1-4 could form 1:2 host-guest complexes with CB[10]in aqueous *** of 1 in the presence of 0.5 *** CB[10]selectively produced a head-to-tail(anti-HT)photodimer *** for 2-4,CB[10]acted as a nanoreactor accelerating their photodimerization reaction in *** results suggest that photodimerization of azaanthracene derivatives could be promoted by the CB[10]-based host-guest strategy with high efficiency and selectivity.
