NOVELTY - Benzoterrylene derivative, is new.    USE - In a composition which is useful in molded article; in polymeric resin composition, in dye or pigment for coloring a polymeric resin and in luminescent solar collector (claimed); for coloring organic and inorganic materials, for making paints, inks, coatings; for security-marking purposes; for labeling objects; for converting light frequencies; for passive display elements; as starting materials for superconducting organic materials; as fluorescent dyes for machine-readable markings; as laser dyes; and for preparing non-impact printing toners, color filters, organic photoreceptors, electroluminescence and photoluminescence elements.    ADVANTAGE - The benzoterrylene derivatives absorb light at longer wavelengths and have a higher quantum yield. The benzoterrylene has a fluorescent quantum yield of at least 70 (preferably 90)%.    DETAILED DESCRIPTION - Benzoterrylene derivative of formula (I), is new.    R1, R2, R15, and R16=H, alkyl, cycloalkyl, aryl, aryloxy, thiophenyl, carbonylalkyl, carbonylphenyl, alkyl carboxylic acid, or carboxylalkyl (each optionally substituted with T1);    T1=alkyl, cycloalkyl, aryl, aryloxy, thiophenyl, carbonylalkyl, carbonylphenyl, alkyl carboxylic acid, carboxylalkyl, halogen, cyano, oxo, nitrogen, hydroxyl, epoxy, amino, carboxyl or thiono);    R3-R14=halogen, cyano, hydroxyl, hydrogen, alkyl, cycloalkyl, aryl, aryloxy, thiophenyl, carbonylalkyl, carbonylphenyl, alkyl carboxylic acid, or carboxylalkyl (each optionally substituted with T1);or    R4+R5, R6+R7, R10+R11 and R12+R13=-CH=CH-, furan-2,5-dione-3,4-diyl or compound of formula (i);    Y1-Y4=O or NR16;and    R1+R16 and R2+R16=ring structure selected from benzene-1,2-diyl, or naphthalene-1,8-diyl.    INDEPENDENT CLAIMS are included for the following:    (1) a composition comprising a polymeric resin and compound (I);    (2) a method of coloring a polymeric resin, involving step of incorporating compound (I) into the polymeric resin;    (3) a luminescent solar collector, comprising: a sheet which comprises a polymer and compound (I) and a light energy converter which is operatively connected to the sheet;    (4) preparing a benzoterrylene (I).
