RESUMEN
Anthracene derivatives self-assemble into fibers with a high molecular order, as is evidenced by probing the structure with energy-trapping tetracene analogues. Efficient energy transfer processes involving tens to hundreds of donors per acceptor and high emission quantum yields are outstanding characteristics displayed in these self-assembled fibers.
RESUMEN
[structure: see text] Rod-shaped 2,3-di-alkoxytetracenes, soluble in common organic solvents, have been synthesized and studied for their gelling ability in organic solvents and their unusual UV-visible spectroscopic properties.
RESUMEN
[reaction: see text] Irradiation of 5,12-didecyloxytetracene (1) leads to photodimers P(1) (planosymmetric) and P(2) (centrosymmetric). P(1) is characterized by naphthalene excimer fluorescence, whereas P(2) emits naphthalene monomer fluorescence.
