Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

Ru(II) polypyridine complexes: photophysics, photochemistry, eletrochemistry, and chemiluminescence

BODIPY dyes and their derivatives: syntheses and spectroscopic properties.

In this review, we highlight the use of organic photoredox catalysts in a myriad of synthetic transformations with a range of applications. This overview is arranged by catalyst class where the photophysics and electrochemical characteristics of each is discussed to underscore the differences and advantages to each type of single electron redox agent. We highlight both net reductive and oxidative as well as redox neutral transformations that can be accomplished using purely organic photoredox-active catalysts. An overview of the basic photophysics and electron transfer theory is presented in order to provide a comprehensive guide for employing this class of catalysts in photoredox manifolds.

Organic Photoredox Catalysis

The world of organic luminophores has been confined for a long time to fairly standard biological labeling applications and to certain analytical tests. Recently, however, the field has undergone a major change of direction, driven by the dual needs to develop novel organic electronic materials and to fuel the rapidly emerging nanotechnologies. Among the many diverse fluorescent molecules, the Bodipy family, first developed as luminescent tags and laser dyes, has become a cornerstone for these new applications. The near future looks extremely bright for "porphyrin's little sister".

The Chemistry of Fluorescent Bodipy Dyes: Versatility Unsurpassed

In the steadily expanding field of fluorescent dyes, labels and electroluminescent materials difluoroboron-dipyrromethenes play a prominent role The review highlights recent advances made with these boron-stabilized cyanine dyes The chemistry at the boron atom and increase of delocalization on the organic core allows one to address the problems of Stokes’ shifts, colours and emission wavelengths spanning from green to the NIR The outcome is a diversity of molecules prepared by different strategies and exhibiting interesting and tunable spectroscopic, electrochemical and chemical properties This perspective article describes the scope and spectroscopic attributes of this new class of fluorescent dyes amenable to applications in various disciplines

The chemistry of Bodipy: A new El Dorado for fluorescence tools

Organische Luminophore wurden lange nur in biologischen Markierungsverfahren und bestimmten analytischen Nachweisen angewendet, doch in jungster Zeit werden auch neuartige organische elektronische Materialien und Farbstoffe fur die aufstrebende Nanotechnologie entwickelt. Unter vielen verschiedenartigen Fluoreszenzfarbstoffen erwiesen sich dabei die Bodipy-Farbstoffe, die zunachst als Lumineszenzmarker und Laserfarbstoffe entwickelt worden waren, als besonders geeignet. Dieser “kleinen Schwester des Porphyrins” scheinen grose Perspektiven offenzustehen.
