Description
Summary:[Display omitted] •Highly soluble host material for blue fluorescent organic light-emitting diodes.•Alkyl free molecular design of anthracene host material for soluble devices.•Ortho linked aromatic structure for good solubility in organic solvents. An alkyl free anthracene based host material, 9-([1,1′:2′,1″-terphenyl]-2-yl)-10-phenylanthracene (AnTP), was developed as a soluble host material for solution processed blue fluorescent organic light-emitting diodes by increasing the solubility of anthracene type host material using a twisted aromatic substituent. The good solubility of AnTP even without any alkyl substituent allowed solution coating of AnTP based emitting layer and fabrication of solution processed blue fluorescent organic light-emitting diodes with a current efficiency of 3.7cd/A.
