Novel Polycyclic Compound

A novel type of polycyclic compound, a structure of the compound is represented by formula (1) or formula (2),

• A-R1—B—R2—C—R3-D (1),
• A-R1—B—R2-D-R3—C (2),
• including at least one visible light or fluorescence emitting group, and at least an additional ultraviolet light absorbing group, wherein the visible light or fluorescence emitting group is R2—C—R3-D or R2-D-R3—C;
• the ultraviolet light absorbing group is A-R1—B;
• R1 to R3 are each independently a bond or/and any divalent linking group;
• A, B, and C are each independently a benzene ring, a benzo-carbocyclic ring, a nitrogen-containing 5˜7 membered heterocyclic ring, or a nitrogen-containing 5˜7 membered benzo-heterocyclic ring, which substituted by R4;
• D is a substituted 5˜7 membered heterocyclic ring or a 5˜7 membered benzo-heterocyclic ring composed of carbon, nitrogen, oxygen, and sulfur atoms, wherein, each substituent of the ring on carbon atom is selected from the group consisting of hydrogen, hydroxyl, oxo, thio, thiol, amine, imino, C1˜C8 linear or branched alkyl or alkenyl, and R4, and the substituent of the ring on nitrogen atom is selected from the group consisting of hydrogen, hydroxyl, oxo, and linear or branched C1˜C8 alkyl;
• R4 is one or more substituents, each independently selected from the group consisting of hydrogen, halogen, hydroxyl, amino, nitro, cyano, linear or branched C1˜C18 alkyl, alkenyl or alkoxy, unsubstituted or substituted phenyl, SR5, SO2R5, SO3R5, COOR5, COR5, OCOR5, C(O)NR6R7, SO2NR6R7, and NR6R7, wherein R5, R6, and R7 are each independently hydrogen and linear or branched C1˜C8 alkyl groups;
• R4 and adjacent R4, or adjacent ring, together form 3-6 atom fused carbocyclic or fused heterocyclic ring.
