1.
Wan W, Li A
Int J Mol Sci . 2023 Apr; 24(8). PMID: 37108652
Our understanding of molecules has stagnated at a single quantum system, with atoms as Newtonian particles and electrons as quantum particles. Here, however, we reveal that both atoms and electrons...

Yu Z, Li X, Wan W, Li X, Fu K, Wu Y, et al.
Chem Sci . 2021 Jun; 12(9):3146-3151. PMID: 34164081
Balancing the rigidity of a π-conjugated structure for strong emission and the flexibility of liquid crystals for self-assembly is the key to realizing highly emissive liquid crystals (HELCs). Here we...

Wan W, Li A
Angew Chem Int Ed Engl . 2020 Aug; 59(49):21915-21919. PMID: 32776413
Monitoring multiple molecular probes simultaneously establishes their correlations and reveals the holistic mechanism. Current fluorescence imaging, however, is limited to about four colors because of typically circa 100-nm spectral width....

Wan W, Li A
Angew Chem Int Ed Engl . 2019 Jul; 58(39):13739-13743. PMID: 31269318
The currently understood principles about light-molecule interactions are limited, and thus scientific scope beyond current theories is rarely harvested. Herein we demonstrate supracence phenomena, in which the emitted photons have...

Chen J, Ziegler A, Zhao B, Wan W, Li A
Chem Commun (Camb) . 2017 Apr; 53(36):4993-4996. PMID: 28425540
Folding-unfolding imparts fluorescence dual color switching, thus a novel concept to switch fluorescence between two distinct colors while avoiding traditional bond rupturing and bond forming in photoswitching. Because folding and...

Wang J, Lv Y, Wan W, Wang X, Li A, Tian Z
ACS Appl Mater Interfaces . 2016 Feb; 8(7):4399-406. PMID: 26859429
As a very sensitive technique, photoswitchable fluorescence not only gains ultrasensitivity but also imparts many novel and unexpected applications. Applications of near-infrared (NIR) fluorescence have demonstrated low background noises, high...

Zhang Y, Zhang K, Wang J, Tian Z, Li A
Nanoscale . 2015 Oct; 7(46):19342-57. PMID: 26445313
Although fluorescence offers ultrasensitivity, real-world applications of fluorescence techniques encounter many practical problems. As a noninvasive means to investigate biomolecular mechanisms, pathways, and regulations in living cells, the intrinsic heterogeneity...

Wan W, Zhu M, Tian Z, Li A
J Am Chem Soc . 2015 Mar; 137(13):4312-5. PMID: 25774573
A pair of reversible photochemical reactions correlates their reactant and product specifically, and such a correlation uniquely distinguishes their correlated signal from others that are not linked by this reversible...

Wu Y, Zhu W, Wan W, Xie Y, Tian H, Li A
Chem Commun (Camb) . 2014 Oct; 50(91):14205-8. PMID: 25283709
Photoswitching of bis(dithiazole)ethene can be regulated by Hg(II) ions and EDTA in a "lock-and-unlock" manner. The molecular photoswitch provides an enzyme-like binding pocket that selectively binds specifically to mercury ions,...

Shaller A, Wan W, Zhao B, Li A
Chemistry . 2014 Aug; 20(38):12165-71. PMID: 25111357
The fluorescence brightness of a molecular probe determines whether it can be effectively measured and its water solubility dictates if it can be applied in real-world biological systems. However, molecules...
