Fluorescent chromophores nicknamed BOPHY are provided. The chromophores may be readily synthesized in two steps from readily available reagents via the coupling of a pyrrole aldehyde or ketone with hydrazine, followed by reaction with BF3. The resultant symmetric and dimeric tetracycle is comprised of two BF2 units in six-member chelate rings, appended by pyrrole units on the periphery. The quantum yield of fluorescence for the unmodified compound and the tetramethyl variant are near unity, with values 95 and 92% respectively in CH2Cl2.

Half-phthalocyanine-like chelates, such as bis(iminoisoindolinyl)azomethene (BIAM), bis(oxoisoindolinyl) azomethene (BOAM), are provided, as well as chelates based thereon. Methods for synthesizing and synthetically modifying the novel chelate compounds are also provided. The half-phthalocyanine-like chelates have useful properties, particularly with regard to UV-visible absorption and emission as well as electron or energy transfer.

The present invention relates to novel coordination complexes, methods for synthesizing and identifying coordination complexes, using combinatorial techniques, and assaying their activity. In certain embodiments, the invention relates to a library comprising a plurality of platinum-containing coordination complexes represented by the general formula {PtLnA(4-n)}, wherein, independently for each occurrence, each L is a non-labile ligand under standard conditions, each n is equal to 1, 2 or 3; each A is a labile ligand under standard conditions; and each Pt is Pt(II) or Pt(IV); provided that when Pt is Pt(IV), two additional ligands in the trans axial positions of the general formula depicted are present; and at least one of the plurality of platinum-containing coordination complexes is represented by the formula wherein, independently for each occurrence: X represents halogen or other labile ligand under standard conditions; W represents S, N, or P; Y represents —OR7, —SR7, a halogen or —N(R9)R10; R9 and R10, each independently, represent —H, alkyl, alkenyl, —(CH2)n—R7, or R9 and R10, taken together with the N atom to which they are attached complete a heterocycle having from 4 to about 8 atoms in the ring structure, all optionally substituted; L represents a non-labile ligand under standard conditions; R7 represents —H, alkyl, aryl, cycloalkyl, cycloalkenyl, heterocycle or polycycle; the ligand V comprises W, Y, and a heterocycle having from 4 to about 8 atoms in the ring structure, optionally aromatic and optionally substituted; and the symbol represents a single or a double bond.
