Modulating Molecular Aggregation of Luminogens: Bridging the Gap Between Solutions and Solids

In the past two decades, the advancement of aggregation-induced emission (AIE) has greatly advanced our understanding of organic luminescence and facilitated the application of organic luminescent materials. AIEgens emit weakly in solutions but strongly in aggregated states. This significant difference in luminescence between solutions and aggregated states of AIEgens has shown that there is much to explore in the mesoscopic world (the intermediary phase). Accordingly, the research paradigm is shifting towards aggregate science. The path to new aggregate materials relies not only on molecule syntheses but also on the control of molecular aggregation. Molecular aggregation bridges the gap between solutions and solids, which is of great significance for developing aggregate science. In this perspective, we outline three general strategies for managing molecular aggregation to stimulate new ideas and provide guidance on controllable molecular aggregation

Aggregation-induced emission materials based on restriction of intramolecular vibration

Aggregation-induced emission (AIE) is a photophysical phenomenon wherein luminescent materials exhibit weak emission in solution but strong emission after aggregation. This phenomenon has garnered significant attention in the realm of multifunctional luminescent materials. Specifically, AIE molecules, which operate through the restriction of intramolecular vibration (RIV) mechanism, have emerged as a pivotal constituent of AIE materials, captivating the interest of both academia and industry. This review aims to present a comprehensive overview of recent advancements in the domain of RIV-type AIE and its associated areas. It encompasses a survey of the classifications, molecular design strategies, and mechanisms underlying RIV-type AIE molecules. Furthermore, the review delves into the prospects and challenges encountered in the realm. We hope this review can provide novel insights into the theory, materials, and applications in the field of biochemistry and organic photoelectric

The Weakening Position of University Graduates in Singapore's Labor Market: Causes and Consequences

Pulled along by global developments, Singapore is rapidly developing a "knowledge-based economy." Between 1990 and 2000, gross domestic product more than doubled (in constant dollars), and the number of managerial and professional jobs almost doubled. Such advances should be a boon to middle-class Singaporeans, but, instead, they find themselves under increasing economic pressure despite the increased need for educated labor and the surplus of manual labor. On the basis of analysis of available data, the article documents the deteriorating relative position of the well-educated in the labor market and explores the role of migration in that process.
