“…Several researchers have built on these findings, and many transition metal complexes have since been reported to efficiently catalyze ATRP using visible light. 15,16 More recently, organic photoredox catalysts 17 (PCs) based on perylene, 18 phenothiazine, 19 dihydrophenazine, 20 and phenoxazine 21 chromophore motifs have been developed to mediate organocatalyzed ATRP (O-ATRP) to produce polymers with controlled MW, high initiator efficiency (I* = MW theo /MW exp ), and low Đ ( Figure 1) while avoiding the possibility for incorporating metal contamination into the polymer product. 22,23 Since the seminal reports on O-ATRP, PC structural modifications, 24 photophysical characterizations, [25][26][27] solvent effects, 28 light intensity modulations, 29 and synthesis of higher-order polymer architectures [30][31][32] have been reported to advance the O-ATRP processes.…”

Photoinduced organocatalyzed atom-transfer radical polymerization (O-ATRP) is a controlled radical polymerization methodology that can be mediated by organic photoredox catalysts under the influence of light. However, typical O-ATRP systems require relatively high catalyst loadings (1000 ppm) to achieve control over the polymerization. Here, new core-extended diaryl dihydrophenazine photoredox catalysts were developed for O-ATRP and demonstrated to efficiently operate at low catalyst loadings of 5-50 ppm to produce polymers with excellent molecular weight control and low dispersity, while achieving near-quantitative initiator efficiency. Photophysical and electrochemical properties of the catalysts were computationally predicted and experimentally measured to correlate these properties with improved catalytic performance. Furthermore, these catalysts were utilized to synthesize materials with complex architectures, such as triblock copolymers and star polymers. To demonstrate their broad utility, polymerizations employing these catalysts were successfully scaled up to 5 g and revealed to efficiently operate under air.

“…Doctor-patient interaction takes place in a social context characterised by relationships of power, trust, and dependence, which have a significant impact on the practical ability of patients to exercise autonomous choice. 109 As scholars of clinical ethics have long been aware, conceptions of consent rooted primarily in autonomy are inherently limited in their ability to deal with inequality. Two assumptions underlie these models: firstly, that patients who are given scientific information on the benefits and risks of treatment can make decisions for themselves and, secondly, that 'physicians should not have an investment in the decisionmaking process or in the decision made.'…”

Responsiveness and the Role of Rights in Medical Law: Lessons from Montgomery†

Over time, medical law has moved away from paternalism in favour of an approach grounded in patients’ rights. Using Montgomery v Lanarkshire Health Board (2015) as a case study, we offer a deeper analysis of this emerging approach. We argue that patients’ rights should be evaluated in terms of their contribution to making medical law more socially responsive, by developing it to give effect to social needs and aspirations pertaining to health care. Although rights can play an important role in achieving social responsiveness, they also carry the risk of entrenching approaches unrepresentative of patients’ actual needs and empirical realities. This is evident in Montgomery, where the law, despite being derived from General Medical Council (GMC) guidance, has effects that differ significantly from the GMC’s goals. Drawing on socio-legal literature, we outline a new approach for guiding the use of rights in medical law focused on the functional consequences of rights in facilitating patients’ aspirations, and the capacity of rights to respond to social and institutional contexts in which medical interaction occurs. We conclude by showing how this approach, applied to informed consent, would produce a different and arguably a superior duty, providing a sounder basis for responding to patient needs.
