Article Abstract
Organic afterglow materials have drawn increasing attention for their great potential in practical applications. Until now, most of them just show the lifetimes in milliseconds or seconds, while the realization of long persistent luminescence (LPL) lasting for minutes or even hours is difficult. In 2017, Adachi and Kabe successfully realize the LPL with a duration longer than 1 hour in a purely organic system, which can be even comparable to some excellent inorganic materials. However, partially for the unclear structure-property relationship, organic LPL materials are still rather scarce, especially for the stable ones in air or aqueous solution. In this review, we present the recent progress in organic LPL, mainly focusing on the material design strategy and internal mechanism. It is anticipated that the deep understanding can be beneficial for the further development of organic LPL materials with good stability in air and even aqueous phase.

Long-persistent luminescence (LPL) materials have applications from safety signage to bioimaging; however, existing organic LPL (OLPL) systems do not align with human scotopic vision, which is sensitive to blue light. We present a strategy to blueshift the emissions in binary OLPL systems by upconverting the charge-transfer (CT) to a locally excited (LE) singlet state. Through rigorous steady-state and time-resolved photoluminescence spectroscopy and wavelength-resolved thermoluminescence measurements, we provide the direct experimental evidence for this upconversion in OLPL systems featuring small energy offsets between the lowest-energy CT and LE singlet states.

Metal-organic frameworks (MOFs) have been considered as ideal platforms to achieve long persistent luminescence (LPL), to utilize as optical recording devices, security systems and sensors. Despite the rapid emergence, it is still a challenge to develop single-component red LPL MOFs. In this work, two hetero-ligand MOFs are synthesized using a D-π-A-type ligand (source of red phosphorescence) and a monocyclic carboxylic ligand (appropriate void constructer), which show efficient red LPL after removal of wide excitations at ambient conditions.

This research paper compares fertility traits, health indicators and health management routines of Swiss dairy farms characterized by short long productive lifespans (SPL LPL). We evaluated whether a longer productive lifespan will result in poorer cow health based on herdbook data from breeders associations (n = 142), farm questionnaire data (n = 67), veterinary treatment data (n = 64) and data obtained during farm visits (n = 30). Dairy farms were selected in such a way that they contrasted in terms of length of productive lifespan, but were representative of the Swiss dairy sector.

Light-responsive porous liquids (LPLs) attract significant attention for their controllable gas uptake under light irradiation, while their preparation has remained a great challenge. Here we report the fabrication of type II LPLs with enhanced light-responsive efficiency by tailoring the host's functionality for the first time. The functionality of light-responsive metal-organic cage (MOC-RL, constructed from dicopper and responsive ligands) is modified by introducing the second long-chain alkyl ligand, producing MOC-RL-AL as a new host.
