Exciplexes of dimethyldiphenylacetylenes have the highest light production of all recombination exciplexes of diphenylacetylenes known so far. The studied compounds and their analogs as a class may be considered as potential blue emitters for organic electroluminescent systems, including magnetosensitive ones.</p></abstract><trans-abstract xml:lang="ru"><p>На примере трех соединений показано, что при рентгеновском облучении в неполярном растворе донорно-замещенные диметил- и диметокси-(дифенилацетилены) образуют эксиплексы в паре с N,N-диметиланилином через рекомбинацию соответствующих ион-радикалов с интенсивной магниточувствительной полосой люминесценции. Эксиплексы диметилдифенилацетиленов обладают максимальным световыходом по сравнению со всеми известными рекомбинационными эксиплексами дифенилацетиленов.
