Disclosed is a cross-coupling reaction method which forms a chemical bond selected from C—N, C—B, C—C, C—O and C—S bonds, the method comprising:
preparing an aromatic compound (1) having a leaving group;
preparing a compound (2) capable of undergoing a cross-coupling reaction selected from an aromatic amino compound (2-1), a diboronic acid ester or the like (2-2), an aromatic boronic acid or the like (2-3), an aromatic compound (2-4) having a hydroxyl group and an aromatic compound (2-5) having a thiol group; and
performing a cross-coupling reaction of the compound (1) with the compound (2) in the presence of a palladium catalyst, a base and a compound (4) having a carbon-carbon double bond or a carbon-carbon triple bond, in the absence of a solvent.

five zinc porphyrin antenna moieties absorb light, exchange excitation energy, and ultimately decay by normal photophysical processes. Their excited-state lifetimes are long enough to permit harvesting of the excitation energy for photoinduced chargeseparation or other work. However, when acid is added, a pH-sensitive dye moiety is converted to a form that rapidly quenches the first excited singlet
A rhodamine appended hexaphenylbenzene based derivative 5 has been designed and synthesized, which displays through bond energy transfer in the presence of picric acid in MeOH and serves as a "turn on" sensor for picric acid.

compounds was investigated in THF. Among the different anions, significant changes in the fluorescence spectra of HPB-1 and HPB-2 were observed in the presence of only F− ions. The interaction ratios of HPB-1 and HPB-2 with F− ions were determined to be 1 : 1 and the binding constants (KA) were found to be 0.0417 M−1 and 0.982 M−1 for HPB-1 and HPB-2, respectively. The LOD values were calculated as
