The present invention relates to organic light emitting elements, comprising thermally activated delayed fluorescence (TADF) emitters and/or hosts on basis of phthalimide and naphthalimide materials, which have a sufficiently small energy gap between S.sub.1 and T.sub.1 (E.sub.ST) to enable up-conversion of the triplet exciton from T.sub.1 to S.sub.1. The organic light emitting elements show high electroluminescent efficiency.

The present application relates to an electronic device comprising a heteroaromatic compound of a formula (I) as functional material, in particular as electron-transport material and as matrix material for emitter compounds. ##STR00001##

A method of solubilizing a composition, such as an organic manufactured photochromic dye that is free of carcinogens, non-mutagenic, non-toxic to human skin in any concentration, and suitable for application to, and absorbable by, human skin. The photochromic dye is suitable to be applied directly to human skin, and which dye is configured to indicate exposure to UV rays. The composition is configured to change color upon exposure to UVA, UVB and/or UVC rays. The composition can be used with other compositions, such as sunscreen, and be applied to human skin prior to application of the sunscreen, or, formulated with the sunscreen such that when the active ingredients of the sunscreen diminish, the photochromic dye will change color to generate a visual indicator of this condition.

The presently-disclosed subject matter includes azetidine-substituted fluorescent compounds, where the compounds may be used as probes, dyes, tags, and the like. The presently-disclosed subject matter also includes kits comprising the same as well as methods for using the same to detect a target substance.
