Journal ArticleDOI
Highly Efficient Near-Infrared Organic Light-Emitting Diode Based on a Butterfly-Shaped Donor-Acceptor Chromophore with Strong Solid-State Fluorescence and a Large Proportion of Radiative Excitons
TL;DR: Experimental and theoretical investigations were carried out to understand the excited-state properties of PTZ-BZP, a butterfly-shaped D-A compound that breaks through the limit of 25 % in conventional fluorescent OLEDs.
Journal ArticleDOI
Employing ∼100% Excitons in OLEDs by Utilizing a Fluorescent Molecule with Hybridized Local and Charge-Transfer Excited State
Weijun Li,Yuyu Pan,Ran Xiao,Qiming Peng,Shitong Zhang,Dongge Ma,Feng Li,Fangzhong Shen,Yinghui Wang,Bing Yang,Yuguang Ma +10 more
TL;DR: In this paper, a twisting donor-acceptor triphenylamine-thiadiazol molecule (TPA-NZP) exhibits fluorescent emission through a hybridized local and charge-transfer excited state (HLCT), which is demonstrated from both fluorescent solvatochromic experiment and quantum calculations.
Journal ArticleDOI
Highly efficient near ultraviolet organic light-emitting diode based on a meta-linked donor-acceptor molecule.
Haichao Liu,Qing Bai,Liang Yao,Haiyan Zhang,Hai Xu,Shitong Zhang,Weijun Li,Yu Gao,Jinyu Li,Ping Lu,Hongyan Wang,Bing Yang,Yuguang Ma +12 more
TL;DR: In this paper, a near ultraviolet emitter with a meta-linked donor-acceptor (D-A) structure between triphenylamine (TPA) and phenanthroimidazole (PPI), mTPA-PPI, was designed and synthesized.
Journal ArticleDOI
Excimer-induced high-efficiency fluorescence due to pairwise anthracene stacking in a crystal with long lifetime
Haichao Liu,Liang Yao,Bao Li,Xian Kai Chen,Yu Gao,Shitong Zhang,Weijun Li,Ping Lu,Bing Yang,Yuguang Ma +9 more
TL;DR: An anthracene-based material, 2-(anthracen-9-yl)thianthrene (), whose crystal exhibits excimer fluorescence with an unexpected high luminous efficiency and long lifetime, will update the traditional view that excimers are poorly efficient in photoluminescence.
Journal ArticleDOI
Highly Efficient Nondoped Green Organic Light-Emitting Diodes with Combination of High Photoluminescence and High Exciton Utilization.
Chu Wang,Xiang-Long Li,Yuyu Pan,Shitong Zhang,Liang Yao,Qing Bai,Weijun Li,Ping Lu,Bing Yang,Shi-Jian Su,Yuguang Ma +10 more
TL;DR: This work designed and synthesized CzP-BZP with this efficeient combination of high PL efficiency of η(PL) = 75% in the solid state and maximal exciton utilization efficiency up to 48% in OLED, and aims to design next-generation, low-cost, high-efficiency fluorescent OLED materials.
