Abstract: The present invention relates to compounds according to formula I, wherein: R1 is a cyclopentadienyl moiety or a moiety comprising a cyclopentadienyl ring structure; R2 is a moiety M(R5)2 or MR5, wherein M is a metal selected from hafnium, titanium or zirconium, and R5 is F, Cl, I, Br or an alkyl-moiety comprising 1 to 10 carbon atoms, preferably methyl, benzyl, butadiene or pentadiene; R3 is H, an alkyl or aryl moiety comprising 1 to 10 carbon atoms, or a moiety comprising N or O and 1 to 15 carbon atoms; R4 is H, an alkyl or aryl moiety comprising 1 to 10 carbon atoms, or a moiety comprising N or O and 1 to 15 carbon atoms, or a halogen; wherein if R3 is H, R4 is a moiety other than H, and if R4 is H, R3 is a moiety other than H; each R6 is individually selected from H, a halogen, an alkyl moiety, an aryl moiety, a halogen-substituted alkyl moiety, a halogen-substitute d aryl moiety, an alkoxy moiety, a siloxy-moiety, or a nitrogen-containing moiety, preferably H.

Abstract: A luminescent solar collector comprises a sheet and a light energy converter operatively connected to the sheet, the sheet comprising a thermoplastic polymer and dispersed therein at least two dyes A and B; wherein dye A is a fluorescent dye of Formula (I) and dye B is either a perylene dye of Formula (II) or a diketopyrrolopyrrole dye of Formula (III): wherein R, m, R1, R2, R3, R4, and k are as described herein. The luminescent solar collector has improved output.

Abstract: Disclosed are fluorescent dye compounds of Formula (I): wherein R1, R2, and G are as described herein. The fluorescent dyes are suitable for use in luminescent solar collectors or as a colorant. Methods of making the fluorescent dyes and luminescent solar collectors comprising them are also described.

Abstract: A luminescent solar collector contains a first fluorescent dye and a dye compound of Formula (I) or (II): where R, R?, m, and k are as described herein. The luminescent solar collector has improved output.
