Disclosed are compounds, methods, reagents, systems, and kits for the preparation and utilization of monomeric or polymeric metal-based compounds. These metal-based compounds are organometallic catalysts composed of substituted dipyrrin ligands bound to transition metals. C—H bond functionalization catalysis can be performed with the disclosed organometallic catalysts to yield C—N bonds to generate substituted bicyclic, spiro, and fused nitrogen-containing heterocycles, all common motifs in various pharmaceutical and bioactive molecules.

An intermediate of biliverdin, and preparation method and use thereof includes applying a compound represented by formula 2 as a raw material; R is hydrogen, C.sub.1-C.sub.5 alkyl, or benzyl; “” at positions A and B independently represent a single bond or a double bond; when “” represents a single bond, R.sub.1 or R.sub.2 connected to the single bond is selected from one of tosyl, p-toluenesulfonyl, phenylsulfonyl, phenylsulfinyl; and when “” represents a double bond, R.sub.1 or R.sub.2 connected to the double bond is hydrogen.

Described herein are embodiments of squarylium compounds for use as filters in light-emitting and/or display devices. One problem of known quarylium dyes is that strong nucleophiles can attack the electron-deficient cyclobutene ring which can lead to a loss of the dye's colour. Another potential drawback with squaraine dyes can be their tendency to form aggregates, which can lead to a substantial broadening of their absorption bands. Use of the present compounds in filters address these problems. The squarylium compounds of the present invention have the following formulas: ##STR00001##
