An organic material consisting of a π-conjugated molecule which is in a liquid form at ambient temperature and use thereof are provided. The ambient temperature liquid-form organic material according to the present invention consists of a π-conjugated molecule having 2 or more side chains, the 2 or more side chains are same or different side chains selected from the group consisting of a branched alkyl chain, an alkyl chain having a polymerization site at a terminal, an oligosiloxane chain, a fluorocarbon chain, an oligoethylene glycol chain and derivatives thereof, and each of the 2 or more side chains is bound directly or via a substituent to the π-conjugated molecule.

functioning liquidphotonupconverting system is developed. A rationally designed triplet sensitizer (branched alkyl chain-modified Pt(II) porphyrin) is homogeneously doped in energy-harvesting liquid acceptors with a 9,10-diphenylanthracene unit. A significantly high upconversion quantum yield of ∼28% is achieved in the solvent-free liquid state, even under aerated conditions. The liquid upconversion
