Journal ArticleDOI
A H-bond strategy to develop acid-resistant photoswitchable rhodamine spirolactams for super-resolution single-molecule localization microscopy
Qingkai Qi,Weijie Chi,Yuanyuan Li,Qinglong Qiao,Jie Chen,Lu Miao,Yi Zhang,Jin Li,Wei Ji,Tao Xu,Xiaogang Liu,Juyoung Yoon,Zhaochao Xu +12 more
TL;DR: In this article, a series of acid-resistant rhodamine spirolactams with accelerated ring-closing reactions from fluorescent xanthyliums to non-fluorescent spiactams, endowing them with good photoswitchable properties even in acidic environments.
Journal ArticleDOI
Energy Migration Upconversion in Manganese(II)-Doped Nanoparticles
Xiyan Li,Xiaowang Liu,Daniel M. Chevrier,Xian Qin,Xiaoji Xie,Shuyan Song,Hongjie Zhang,Peng Zhang,Xiaogang Liu,Xiaogang Liu +9 more
TL;DR: Both experimental and theoretical studies provide evidence for Mn(2+) doping in the lanthanide-based host lattice arising from the formation of F(-) vacancies around Mn( 2+) ions to maintain charge neutrality in the shell layer.
Journal ArticleDOI
Molecular Mechanism of Viscosity Sensitivity in BODIPY Rotors and Application to Motion-Based Fluorescent Sensors.
Xiao Liu,Weijie Chi,Qinglong Qiao,Siddhant V. Kokate,Eduardo Peña Cabrera,Zhaochao Xu,Xiaogang Liu,Young-Tae Chang +7 more
TL;DR: It is demonstrated that the transformation energy barrier from the planar conformation to the butterfly conformation is strongly affected by the molecular structures of BODIPY rotors, and plays a critical role in viscosity sensitivity.
Journal ArticleDOI
Nonlinear spectral and lifetime management in upconversion nanoparticles by controlling energy distribution
TL;DR: It is demonstrated that the incorporation of energy distributors, such as surface defects or an extra amount of dopants, into a rare-earth-based host lattice alters the decay behavior of excited sensitizers, thus markedly improving the emitters' sensitivity to excitation power.
Journal ArticleDOI
Optical Torques on Upconverting Particles for Intracellular Microrheometry
Paloma Rodríguez-Sevilla,Yuhai Zhang,Nuno de Sousa,Nuno de Sousa,Manuel I. Marqués,Francisco Sanz-Rodríguez,Daniel Jaque,Xiaogang Liu,Patricia Haro-González +8 more
TL;DR: This work reports on how time-resolved, single particle polarized spectroscopy can be used to determine the orientation dynamics of a single upconverting particle when entering into an optical trap.
