“…Since adamantane (the simplest diamondoid) was first discovered in petroleum in 1933, more diamondoids have been detected in many crude oils (Bender et al, 1986;Williams et al, 1986;Wingert, 1992;Chen et al, 1996;Dahl et al, 1999;Grice et al, 2000;Azevedo et al, 2008), petroleum products (Wang et al, 2006), coals and sedimentary rocks (Imuta and Ouchi, 1973;Aczel et al, 1979;Schulz et al, 2001;Wei et al, 2006a), and gas condensates (Lin and Wilk, 1995;Stout and Douglas, 2004;Sassen and Post, 2008). Furthermore, some higher diamondoids (more than three diamond cages) have been separated and identified from petroleum (Dahl et al, 2003).…”

“…Furthermore, some higher diamondoids (more than three diamond cages) have been separated and identified from petroleum (Dahl et al, 2003). Diamondoid hydrocarbons are more stable than most other hydrocarbons and are resistant to thermal and biological destruction (Aczel et al, 1979;Williams et al, 1986;Wingert, 1992;Grice et al, 2000). Therefore, they have been widely used to determine the thermal maturity of highly mature crude oils (Chen et al, 1996;Li et al, 2000;Zhang et al, 2005), assess the extent of oil cracking (Dahl et al, 1999) and investigate the secondary alteration of crude oils, such as mixing, biodegradation and thermochemical sulfate reduction (TSR) (Dahl et al, 1999;Grice et al, 2000;Wei et al, 2007aWei et al, , 2011.…”

“…By comparing Tables 1 and 2 it becomes clear that generally petroleum fluids contain significantly more [3-,+4-MD] than coals. This is also the case for adamantane and diamantane in coals compared to petroleum fluids (Imuta and Ouchi, 1973;Aczel et al, 1975Aczel et al, , 1979. Wang et al (2006a), Sassen and Post (2008), Zhang et al (2005) and Wei et al (2006c) 3…”

In this review paper, we report the molecular structure, origin, natural occurrence and variety of diamondoid hydrocarbons in petroleum fluids and other fossil fuels. In addition, we present the role of diamondoids as geochemical tools for petroleum characterisation, ways diamondoid molecules are used to play an important role in petroleum evaluation, and may be used to assess origin, extend of biodegradation and thermal maturity, as well as to identify the occurrence of petroleum. The diamondoid-based diagnostic ratios in environment science as well as diamondoid-based diagnostic ratios for petroleum maturity parameters are also presented and discussed. Such diamondoid-based parameters may be used to assess oil source, maturity and biodegradability, providing supporting information, especially when traditional evaluation data are not available or are difficult to interpret. We also report applications and problems associated with diamondoids in petroleum exploration and production. That is the role of diamondoids in petroleum and natural gas production fouling as well as separation, detection and measurements of petroleum diamondoids. We realise that the presence of diamondoids in petroleum has become much more than a chemical curiosity since it has advanced to be a resourceful instrument in petroleum science, biomedicine, materials science and an important family of molecular building blocks in nanotechnology.

“…Owing to their high stability under extreme conditions diamondoids were used as internal standards for liquefaction studies of coal. [154] Chen et al [155] used diamondoids for estimating the age of mature crude oils and they introduced the so-called methyl-diamondoid indices for 1 and 2 that also allow geochemical studies of petroleum, molecular fossils, biodegradation models, and source rocks. [156] Dahl et al [25] showed that the "... diamondoid concentrations increase in a predictable fashion with increasing temperature", and "... the possibility of using their concentrations as a measure of oil destruction."…”

Diamonds are a Chemist's Best Friend: Diamondoid Chemistry Beyond Adamantane

2008

Marilyn Monroe knew that "diamonds are a girl's best friend" but, in the meantime, many chemists have realized that they are also extremely attractive objects in contemporary chemistry. The chemist's diamonds are usually quite small (herein: nanometer-sized "diamondoids") and as a result of their unique structure are unusual chemical building blocks. Since lower diamondoids (up to triamantane) have recently become available in large amounts from petroleum and higher diamondoids (starting from tetramantane) are now also accessible from crude oil new research involving them has begun to emerge. Having well-defined structures makes these cage compounds so special compared to other nanometer-scale diamonds. Selective and high-yielding synthetic approaches to the functionalization of diamondoids gives derivatives that can find applications in, for example, polymers, coating materials, drugs, and molecular electronics.
